  3. 3when you need data to persist beyond lifetime of ec2 instanceamazon elastic block store (Ebs)
  4. 4separate drives from local in store volumes not tied directly to host for ec2EBS volumes
  5. 5configure this for EBS volumessize, type, configurations
  6. 6EBS allows you to take these incremental backups of your datasnapshot

  24. 24can have multiple instances reading and writing simultaneously, Linux file system, and is a regional resourceAmazon EFS

  36. 36non-relational, no sql database. can add and remove attributes at any timedynamo db
  37. 37have simple flexible schemas, tend to run queries on one table rather than multiple tablesnon-relational databases
  38. 38response time for dynamo dbmillisecond
  39. 39one type of structural approach for non-relational databaseskey-value pairs ((data organized into items (keys) and items have attributes (values))
  40. 40data warehousing as a service for big data analytics. allows you to get started with a single api call, good when you need bi data. Can collect data from several sourcesamazon redshift
  41. 41helps you migrate existing databases onto aws securely. migrate between source and target database. source and target databases don't have to be the same typeaws database migration service (DMS)
  42. 42when databases are the same type for migrationhomogenous databases
